7.16 A golf ball of mass 0.045 kg is hit off the tee at a speed of 33 m/s . The golf club was in contact with the ball for 3.90×10−3 s Find the impulse imparted to the golf ball. Find the average force exerted on the ball by the golf club.
Homework Answers
given that
mass of a ball m = 0.045 kg
speed u = 33 m/s
time t = 3.9*10^-3 s
from the impulse momentum theorem
change in momentum = impulse
impulse = m(u-0)
impulse = f avg*t = mu
f avg = 0.045*33/3.9*10^-3
f avg = 380.7 N
